When one of mine had prolonged sneezing episodes he was treated for
sporotrichosis.  It was many years ago so I don't recall any details (&
can't find the records), but the name of the condition was printed on the
back of the vet's (Dr. Elizabeth Hillyer's) card from the Animal Medical
Center in NYC.  Hope this helps.
